I did a custom re-install selected only the studio instruments, did a scan and they are fine. Thanks!

I'm missing CoyoteWT,  DreamStation, Pentagon I, & rgc:audio sfz. 
 
 

CoyoteWT?

What is that?

What version of SONAR are you running X1/X2? 32 or 64bit? Producer/Studio/Essentials?
 
 CoyoteWT is not part of SONAR and I have not heard of sfz being called rgc:audio sfz in years. Are you trying to run older 32bit Dxi synths in 64bit SONAR? If so, the only two on this list that come with SONAR and are installedand supported in the 64bit version are Pentagon and an updated sfz.

Under Insert > Soft Synth, CoyoteWT is the second synth in a list of twenty.
In fact, here's the list I see:

I did nothing particular to install any of these, I only did a normal system install and there they were.  I thought I'd take a look at each one as I was going through the tutorials and found the problem with those four.
 
I'm using Sonar X2 Studio (X2 build306) -x64, on a 64 bit HP Pavilion P6000.
 
 

They are in the DXi section. What other sound software has been installed on this machine? Other software could register DX addons and those addons will appear in the plugin list. Just because the plugin manager sees DX entries in the registry it does not mean they are usable in 64bit SONAR. You can clean up the display by using the plugin manager to exclude plugins.

Oh!  That must explain it. 
 
I have Sonar Home Studio 4 still on my machine, also MuseScore, and Cubase LE 4.  I'll bet it's from Cubase or MuseScore.
 
Thanks a bunch.  I never would have figured that out.
